본 논문에서는 디지털 TV(DTV) 튜너 애플리케이션을 위한 자동 주파수, 이득 및 2단계 진폭 교정 루프를 갖춘 넓은 튜닝 범위의 VCO를 제시합니다. 넓은 튜닝 범위를 포괄하기 위해 완전 디지털 자동 주파수 교정(AFC) 루프가 사용됩니다. AFC 루프 외에 2단계 네거티브-Gm 최적의 negative-G를 제공하기 위해 튜닝 루프가 제안되었습니다.m 넓은 주파수 범위에서 미세한 분해능으로 LC 탱크에 전달됩니다. 거친 음수-G에서m 튜닝 루프, 활성 네거티브-G의 수m 셀은 목표 주파수에 따라 디지털 방식으로 선택됩니다. 미세한 네가티브-G에서m 튜닝 루프, 네거티브-Gm VCO의 바이어스 전압으로 미세하게 조정됩니다. 또한 넓은 튜닝 범위에서 이득 변화를 보상하기 위해 디지털 VCO 이득 교정 방식을 제안합니다. VCO 튜닝 범위는 2.6GHz(1.7GHz ~ 4.3GHz)이고 전력 소비는 2V 공급 장치에서 4mA ~ 1.8mA입니다. 측정된 VCO 위상 잡음은 120MHz 오프셋에서 -1dBc/Hz입니다.

Abstract: This paper presents a wide tuning range VCO with an automatic frequency, gain, and two-step amplitude calibration loop for Digital TV (DTV) tuner applications. To cover the wide tuning range, the fully digital automatic frequency calibration (AFC) loop is used. In addition to the AFC loop, a two-step negative-Gm tuning loop is proposed to provide the optimum negative-Gm to the LC tank in a wide frequency range with a fine resolution. In the coarse negative-Gm tuning loop, the number of active negative-Gm cells is selected digitally based on the target frequency. In the fine negative-Gm tuning loop, the negative-Gm is tuned finely with the bias voltage of the VCO. Also, the digital VCO gain calibration scheme is proposed to compensate for the gain variation in a wide tuning range. The VCO tuning range is 2.6 GHz, from 1.7 GHz to 4.3 GHz, and the power consumption is 2 mA to 4 mA from a 1.8 V supply. The measured VCO phase noise is -120 dBc/Hz at 1 MHz offset.
